The boler is a unique, vintage type of camper trailer. This design was first created by Olecko in 1968. He had an idea for a light weight, streamlined camper trailer, but he did not have the time to draw it out. He asked a friend, Sandor Dusa, to make it for him. Born in Karcag, Hungary, Dusa immigrated to Canada in 1956. He used Olecko’s drawings to create the resulting camper trailer. The result is a modern-day classic.
